Steps to reproduce the issue

We have button padding issues in list layouts for the Cassiopeia template. Install demo data for ease of work further.

1. Create a menu item for the list of articles, in the article settings on the List Layouts tab, select Filter Field --> Tags, then Filter Field --> Month (published). Problems in the screenshot.

2. Create a news feed and a menu item for it, enable the Filter Field and Display Select options in the feed settings on the List Layouts tab. The Filter/Clear element is missing, and the number of elements should be displayed on the right, as it is everywhere in Joomla.
